To all whom it may concern.-

Be it known that 1, JOHN ARTEMAS WRIGHT,

of Keene, in the county of Cheshire and State of New Hampshire, haveinvented a new and useful Improvement in Agricultural Boilers orHeaters; and I do hereby declare that the following is a full and exactdescription of the same, reference being had to the accompanyingdrawings, and to the letters of reference 10 marked thereon.

The object of my invention is to provide novel means for heating waterin, tanks or troughs for cattle, horses,-and for other purposes; and myinvention consists in the device,

I5 which will be fully understoodf-rom the following description andclaim, taken in connection with the annexed drawings, in which- Figure 1is a perspective view of thatpora tion of my device which is designed tobe sub* I 2 merged in a tank of water; Fig. 2, a perspective viewshowing the device represented by .Fig. 1 snbmergedfin atank; alsoshowing a fuel fluid-supply reservoir and a feed-funnel tube. Fig. 3 isa sectional detailshowing a firing-cartridge in the fire-box of theheaters Figs.- 4, 5, and 6 are modifications of, my improvement, showingsome of the diiferent forms in which I contemplate carrying my inventioninto eifect; Fig. 7, a diametrical half- 3 sectional view of afiring-cartridge adapted f0 use in the fire-box of the heater. iReferring to the annexed drawings by letters,A A designate two pipes,which may be made of cast or wrought metal. These pipes.

are connected together by a U-shaped couplingB. The inner end of thelimb A is coupled to a fire-box O, and the other end of the coil iscoupled to said box, as shown in the annexed drawings. This box 0 hasapartition C in it,

4 which subdivides it into a fire-chamber and a heat-expansion chamber,so that the air entering pipe D shall descend into the fire-chambercompartment, pass through the limb A, through the coupling B, and escapethrough the pipe D and its chimney-section D. It will be seen byreference to Fig. 1 that the pipes A A, the coupling B, theexpansionchamber of the fire-box, and the pipes D I) afford a commonflue. The fire-box and por- 5o tions of the pipes D D and the coil arein practice submerged in water in a suitable tub F, leaving the upperends of the pipes D D above the water. The shortest pipe D aifords adescending flue for air to supply oxygen to the flame of a burner orfire-cartridge G, here.-

the ready introduction and removal of this firecartridge. It is obviousthat there may be 7 several coils of pipes, all communicating with outsparks.

The cartridge able porous material which is an absorbent andindestructible by heat. incombustible cartridgeis interiorly hollow andprovided with a vertical tube a. This of the box 0 through the tube D,and the upper end of the tube a is connected to alaterally-extendedbranch tube 6, having a funnel 0 applied to it, wh ichlat ter is adjusted the 1 By reference to Figs. 2 and 3 it will beobserved that I show a cock-by means of which the flow of thehydrocarbon fluid to the cartridge can be regulated; also, that I showat the' upper end of the pipe D the gauze-wire cap w for the purpose ofpositively preventing accidents. by fire.

It is obvious that a fire can be maintained in the fire-box O as long asthere is coal-oil in the reservoir H, the feed of oil being regu latedbymeans of the cock'g.

Instead of subdividing the fire-box 0,1 may use a'single undividedfire-box with a vertical air-supply pipe and connect one limb A to ingthe uptake applied'to it; or Imay employ a single fire-box at one end ofa pipe with. an air-feeding tube applied to this box and an enlarged boxor heat-expansion radiator at the opposite end of said pipe, to whichradiator the uptake is applied; or I may employ a single fire-box withan auxiliary descending tube for supplying air. In all cases I shallpipe to efiec'tually guard against explosion.

One of the main objects of my invention is which can be safely used in abarn and to proheater which is submerged in water, whereby one fire-boxsubdivided in such manuerthat a continuous flue is obtained for heatedair and products of combustion, which latter arewith Preferably this adrip-regulating cock of a coal-oil reservoir H...
